Deployd - 通过AngularJS CORS检索的数据

Question

我目前正在阅读Adam Freeman撰写的"Pro AngularJS".通过这些示例,他让读者使用Angular(当然)和Deployd服务器资源创建了一个体育商店应用程序.Deployd资源设置为返回要填充到模型中的JSON数据.我正在使用NodeJS来运行我的服务器.它目前在端口5000(http://localhost:5000/sportsstore/app.html)上设置.Deployd资源在端口5500(http://localhost:5500/products)上运行.点击Deployd时,响应如下:

[

]

我试图通过使用以下方法检索此数据$http.get:

$http.get("http://localhost:5500/products")
    .success(function (data) { ... })
    .error(function (error) { ... });

但是,这会导致返回错误:

XMLHttpRequest cannot load http://localhost:5500/products. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:5000' is therefore not allowed access. 

研究表明,Angular和CORS存在一些问题,并且必须将头配置为运行跨域请求.结果,我在app.config中添加了以下内容:

$http.defaults.useXDomain = true;
delete $http.defaults.headers.common['X-Requested-With']; // this isn't needed anymore, but was put here as a just-in-case

尽管添加了这些设置,我仍然收到错误.Deployd文档说它是为CORS(跨源请求)自动配置的,只要请求不包含无效的自定义标头,它就会发送相应的标头信息.我很确定我的请求不包含无效的自定义标头:

Accept: application/json, text/plain, */*
Cache-Control: max-age=0
Origin: http://localhost:5000
Referer: http://localhost:5000/sportsstore/app.html
User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.131 Safari/537.36

我的问题:为了让Deployd配置为允许CORS请求处理,我是否需要实施其他配置？本书未指定任何特殊的Angular标头设置或其他任何内容.

Bic,将您的deployd版本升级到版本0.6.10.这对我有用.我现在能够处理get请求.看起来AngularJS代码和Adam Freeman的书并不是错误.

在书中,他确实提到他在http://www.apress.com/9781430264484上包含deployd程序和源代码下载.这是版本0.6.9.我相信它能正常使用它.它比试图找到0.6.10版本更容易..这就是我所做的.如果你想要那个版本,这里是:

https://www.versioneye.com/nodejs/deployd/0.6.10

它不是安装程序,因此您必须将其粘贴到deployd目录中,替换node_modules.
